Specification of Letters Patent.

Patented Jan. t, 191%.

Application filed June 19, 1917, Serial No. 175,651. Renewed June 25, 1918. Serial No. 241,874.

To all whom it may concern:

Be it known that L'HUeEa'r E. HARRIS, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Railway-Rail-Fasten- I marked thereon, which form a part of this Jllll specification.

This invention relates to new and useful improvements in railway rail fastening devices, and the object in view is to produce a simple and eflicient apparatus of this nature, in which means is provided for securely holding the spike from loosening, as a train" passes over the rails.-

Most specifically the present invention comprises a means for holding railwa rails, in which a tie plate, upon which t e rail rests, is provided, upon its under surface, with a series of notches, adapted to receive the inclined end of the wall of the recess formed in the edge of a spike and cooperating therewith to securely bind and hold the spike in its clamping relation with the flange ota rail and tie plate, in the particular moment when the stress comes upon the rail incident to the passing of a train over the rails.

The present invention comprises a simpl and eflicient apparatus of this nature, having various details of construction, combinations and arrangements of parts which will be hereinafter fullv described, shown in the accompanying drawings and then specifically defined in this appended claims.

The invention is illustrated in the accompanying drawings which, with the letters of reference marked thereon. form a part of this specification and in which:

Figure l is a central vertical sectiona view, showing the application of my invention.

Fig. 2 is a top plan view.

Reference now being had to the details of the drawings;

A designates the web of a railway rail, having a flange B, and C is a tie which ma be treated with creosote or other composition, and D designates a metallic tie plate,

cal and adapted to contact with one edge of the flange B of the rail.

A spike, designated by letter I, is provided with a head I, designed to engage over the flange of the rail and isprovided with a notch N formed in its inner edge, the

lower end of the notch having an inclined endwall N. Said spike is provided preferably with a rearcam portion 0 and is convexed, as at J, upon its opposite edge, the said shank portion of the spike being preferably of the shape shown in Fig. 1

of the drawings. Said notches formed in theunder surface of the tie plate are adapted to receive the inclined end of the wall of the recess formed in the spike, the inclined wall of the notch conforming to the inclined end of the recess, so that when the, spike is driven in place in the tie, the spike and plate will interlock, a slight space intervening between the end of the recess and the notch.

The upper urfaceof the plate upon which the flange of the rail rests is rovided with ribs 'll. making a circuitous passageway, whereby anywater which might gatherunderneath the rail may drain ofl', and by this construction the weight of the plate is appreciably reduced and at the same time ample strength afi'orded for the purpose for which the same is intended.

In adjusting the parts, the rail is placed upon the tie plate, with the flan e against the ribs and the spike passingthroughthe opening in the plate and driven intothe tie.

As the spike is driven into the tie one edge of the spike will bear against the marginal edge of the spike aperture and will cause the-plate to move laterally a slight distance,

until the lower marginal edge of the recess in the inner ,edge of the spike, is slightly above the under su'rface'of the plate. The driving of the spike. this distance, will cause the plate D to move laterally a light distance, and with it-the rail, which will be sprung, and when the bottom of the recess passes below the bottom of the plate the rail will spring back, carnying with it the plate,

thus locking the plate and rail securely to the tie.

Plates now employed in railway construction may be provided with the notches without otherwise altering the construction of the plate, thus adapting the invention to standard plates, which are now employed by rail ways. r

When it is desired to remove the spike a claw end of a crow-bar may be inserted underneath the head of the spike and the latter sprung laterally a suflicient distance to permit the notch to clear the marginal edge .of the spike and the flange of the rail.

What I claim to be new is:

1. A railway rail fastening device comprising a tie plate with spike apertures there- 1n, and provided with notches in its under surface, each notch having an inclined Wall, a spike having a recess formed in its inner edge, thelower end wall of the recess being inclined, said spike having a laterally extending head for engagement with the upper surface of the flange of a rail, said spike designed to compact the fiber of the tie as it is driven into the latter, and thereby forcing the plate laterally immediately before the notch in the plate interlocks with the recess in the spike.

2. A railway rail fastening device, comprising a tie plate with spike apertures therein and provided with notches in its under surface each notch having an inclined wall, a spike having a recess formed in its inner edge the lower .end wall of the recess being inclined, said spike having a laterally extending head for engagement with the upper inclined surface of the flange of a rail, the shank portion of the spike underneath said laterally extending head being convexed intermediate the recess and the point of the spike, the outer portion of the spike slightly below said recess being cam shaped and tending to compress the fiber of the tie and force the plate laterally immediately before the notch in the plate interlock with the recess in the spike.

In testimony whereof I hereunto afiix my signature in presence of two witnesses.
